Clancy Pendergast on Friday quit the job he was hired for Feb. 8 with the Raiders so that he could become Cal’s defensive coordinator.

Pendergast left because of an opening that surfaced when Bob Gregory left Cal to become a defensive assistant at Boise State. Pendergast’s ultimate goal was to remain a defensive coordinator, according to a Raiders official, the position he held in the NFL the past six seasons.

The Raiders hired Pendergast to work with defensive backs coach Lionel Washington, a void created by the retirement of long-time defensive backs coach Willie Brown.
